Each group of the contacts (2) is incorporated with positioning members (111) that jointly position the IC package upon the group of the contacts (2).

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an electrical connector, and more particularly to an electrical connector defining a plurality of interconnecting sectors for respectively receiving an individual IC package thereon.

2. Description of Prior Art

Chinese Utility Patent No. 200720045580.1 issued to Liu on Sep. 10, 2008 discloses an electrical connector for interconnecting an IC package and a printed circuit board. The connector includes an insulative housing and a number of contacts received in the housing. The housing features a planar configuration and defines a top surface for supporting the IC package and a bottom surface facing with the printed circuit board. The contacts are retained in corresponding passageways of the housing with contacting arms thereof extending upwardly beyond the top surface of the housing. The housing is further partitioned into four discrete rectangular sections having substantially identical interconnecting area and arranged adjacent with one another. The contacting arms of contacts in diagonal parts extend toward each other to provide balanced force to the IC package.

As the requirement to the performance of a computer system increases, more than one IC packages are required to work together in one computer system so as to meet the requirements. However, the electrical connector in Liu is adapted to only one IC package, thereby can not meet the actual requirements from the customers.

SUMMARY OF THE INVENTION

It is therefore the object of the present invention to provide an electrical connector having more than one interconnecting sectors adapted to receive more than one IC packages thereon.

In accordance with the present invention, an electrical connector for receiving more than one IC packages is provided, which includes an insulative housing having a planar interface with a plurality of passageways defined therein; and a plurality of contacts retained in the passageways respectively and arranged in more than one groups. Each group of the contacts is incorporated with positioning members that jointly position the IC package upon the group of the contacts.

BRIEF DESCRIPTION OF THE DRAWINGS

Other objects, advantages and novel features of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings, in which:

FIG. 1 is a top view of an electrical connector in accordance with a preferred embodiment of the present invention; and

FIG. 2 is a partial assembled, perspective view of the electrical connector in accordance with the preferred embodiment of the present invention.

FIG. 3 illustrates an IC package mounted with the electrical connector shown in FIG. 2.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

FIGS. 1-3 illustrate an electrical connector made in accordance with a preferred embodiment of the present invention for interconnecting many IC packages 3 and a printed circuit board (not shown). The electrical connector includes an insulative housing 1 and a plurality of contacts 2 received in the insulative housing 1.

The insulative housing 1 is featured with a planar configuration. A plurality of passageways 10 are formed in the insulative housing 1 to receive the contacts 2. Each contact 2 has one end contacting with the IC package 3 and the other end contacting with the printed circuit board.

The interface of the housing 1 is partitioned into different sectors separated with blanks and arranged in an array and spaced form each other. The contacts 2 are correspondingly divided into a number of groups to be respectively mounted with the interconnecting sector. A plurality of positioning posts are arranged across the interface such that each sector is incorporated with four

positioning post

11, 13, and 14 so as to position the IC package 3 therebetween. The

positioning posts

11, 13, 14 include three kinds, that is, corner post 14 that has only one positioning member 111, border post 13 that has two positioning members 111, and intersection post 11 that has four positioning members 111. The positioning members 111 of same intersection post 11 or border post 13 are spaced from each other with a gap 114 therebetween so as to provide certain elasticity to the positioning members 111. Each positioning member 111 is formed with an inclined surface 113 at a top end thereof to guide the IC package 3. A latch 112 is formed under the inclined surface 113 to engage with the IC package 3 which is consequently prevented from separating from the electrical connector.

A pair of ear sections 12 is extending at opposite ends of the insulative housing 1 and each ear section 12 is formed with a locating hole 121 for insertion of an alignment pin (not shown) as to facilitate assembly of the electrical connector to the printed circuit board. Each locating hole 12 is equipped with elastic ribs 1211 therein for engaging with the alignment pin.

Although the present invention has been described with reference to particular embodiments, it is not to be construed as being limited thereto. Various alterations and modifications can be made to the embodiments without in any way departing from the scope or spirit of the present invention as defined in the appended claims.
